Hybrid positioning navigation system based on CT three-dimensional model mapping

Abstract

The invention discloses a mixed positioning navigation system based on CT three-dimensional model mapping. The mixed positioning navigation system comprises a CT machine, a storage device, a CDROM reader, a data switch, a Bluetooth docking device, a surgical navigation computer, a keyboard and mouse peripheral device, a liquid crystal display and a navigation probe. The CT machine is a three-dimensional positioning device, plays a role in connecting medical images, surgical tools and surgical targets in a navigation system, plays a very important role in navigation positioning precision and surgical success rate, and has a main role in positioning human tissues and organs and surgical instruments; and the navigation probe is an operation tool. According to the CT three-dimensional model mapping-based hybrid positioning navigation system, hybrid reality fusion can be obtained very visually, the effect of human body perspective is achieved, direct comparison and fusion are achieved, an operation path is accurately measured, calculated and planned, risks are safely and effectively avoided, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of hybrid positioning and navigation, in particular to a hybrid positioning and navigation system based on CT three-dimensional model mapping. Background technique [0002] With the rapid development of computer technology and medical imaging technology, image-guided surgery has gradually replaced the position of open surgery in clinical medical practice. Image-guided surgery includes interventional therapy and direct surgery. Interventional therapy relies on its trauma The advantages of small size and low side effects have gradually become the first choice for the treatment of tumors. Interventional therapy refers to the guidance of C-line, CT, and B-ultrasound, and inserts a thin catheter into the diseased area of ​​the body through a special puncture needle, and injects anticancer drugs through the artery. It is a treatment method in which the drug concentration in the tumor is many times higher than that in the su...

[0002] With the rapid development of computer technology and medical imaging technology, image-guided surgery has gradually replaced the position of open surgery in clinical medical practice. Image-guided surgery includes interventional therapy and direct surgery. Interventional therapy relies on its trauma The advantages of small size and low side effects have gradually become the first choice for the treatment of tumors. Interventional therapy refers to the guidance of C-line, CT, and B-ultrasound, and inserts a thin catheter into the diseased area of ​​the body through a special puncture needle, and injects anticancer drugs through the artery. It is a treatment method in which the drug concentration in the tumor is many times higher than that in the surrounding tissue, so as to improve the anti-tumor effect. The main goal of image-guided interventional therapy is to increase the visualization during intervention and surgery, so that Access to more accurate and thorough ablation of lesions while maximizing the protection of normal tissue; the existing hybrid positioning and navigation system has certain disadvantages in use, and only realizes volume rendering 3D modeling based on the original data of CT MRI scan in DICOM format , can realize multi-angle observation of three-dimensional stereoscopic model display, but it cannot be directly compared with the patient's diseased part. At present, it can only be seen but cannot be accurately compared. It is not intuitive enough and needs further improvement. It has brought certain influence in actual use , for this purpose, we propose a hybrid positioning and navigation system based on CT 3D model mapping
